MACHINE FOR EMBOSSING DESIGNS N WOOD.

SPECIFICATION forming part of Letters Patent No. 448,485, dated March 17, 1891.

Application filed April 22, 189C. Serial No. 349,053. (No model.)

' To cil/ZZ whom, t may concern,.-

Be it known that I, FREDERICK l1. HAW- KINs, a subject of the Queen of Great Britain, residing at 550 East One hundred and fortythird street, in the city of New York, and county and State of New York, have invented certain new and useful Improvements in Machines for Embossing Designs on food or other Material, of which the following is a specification.

My invention has relation to improvements in machines for embossing designs on wood and other material; and it has for its object to provide a machine of the character mentioned thoroughly adapted to emboss all forms and kinds of wood and the like with Various appropriate and ornamental designs.

The improvements will be fully understood from the following description and claims, when taken in connection with the accompanyin g drawings, in whieh Figure l is a side elevation of my improved machine, the parts being illustrated in an operative position with a piece of stock between the embossing-rolls. Fig. 2 is a front elevation of the same. Fig. 3 is a detail plan view of the bed of the machine, the movable pressure elements being removed and the upright standard illustrated in horizontal sections. Fig. 4 is a detail side view illustrating' the relative positions of the embossing-rolls and the piece of stock when adjusted 'for heavy work.

Referring by letter to the said drawings, a indicates the bed or base frame of the machine, which may be cast or otherwise formed in any approved manner. Preferably formed integral with and rising from the bed a is an upright standard C, which is provided at its upper end with an integral forwardly-extend ingV angular branch e', for a purpose presently to be described. This standard C, as illustrated at S in Fig. 3, is provided with an opening or recess at its base, whereby 'a passage is afforded for that class of work which is fed longitudinally through the machine. Mounted on suitable bearings on either side of the rear upper end of the bed or` base frame a is a forwardly-disposed pivoted section g, comprising two arms or branches, and these arms or branches have journaled between them at their forward ends in suitable bearings an embossing die or roll 7L, which rests over the space between the two lower dies h h2," presently to be described, and one of the arms of the section g has suitably mounted upon it a train of gears which trans mit motion from the pulley-shaft to a pinion upon the end of the shaft carrying said embossing roll 7L. By this construction and mounting of the section g it will be seen that its forward and free end is allowed a vertical play of several inches, whereby the dies may be adj usted to emboss stock of various sizes.

Suitably jou rnaled in the forwardly-extending branch t' of the standard G and adjacent to the forward end thereof is a gear-wheel K, upon the ends of the shaft of which are fixed cams m, which bear upon the upper side of and regulate the pressure of the roll 71., journaled in the free end of section g.

The gear K is actuated by a worm-gear Y, mounted on the top of the branche and meshing with said gear K, and mounted on the forwardly-extending portion of the shaft of said worm-gear Y is a hand-wheel 1W, whereby the same maybe readily operated. Fixed on the shaft carrying the gear K is a bandwheel K', to the periphery of which is attached the upper end of a strap V, which may be formed of any approved material, and is attached at its lower end to the free end of the pivoted section g. On each side of the pivoted frame g, adjacent to the forward end thereof, are pivotally-connected hangers n, the lower ends of which are pivotally connectedto the forward ends of bars n', which are suitably mounted in a pivoted manner on each side of the bed a adjacent to the rear upper end thereof. Pivotally connected to the bars n' at a suitable intermediate point are depending tension-bars n2, which in turn have their lower ends pivotally connected at an intermediate point in the length of weight bars or levers n3, which are pivotally connccted to the sides of the bed a adjacent to the forward lower end thereof. These bars n3 are provided with apertures atintermediate points, as illustrated, whereby the lower end of the tension-bar n2 may be adj ustably connected thereto, and the said bars or levers n3 carry at or adjacent to their free ends weights n4, which are provided with bindingscrews or the like, whereby they may be ad justably fixed on the said levers ai. ly this construction it will be seen that I have provided a positive means for exerting a pressure upon and holding the free end of section g down and carrying the engraving-die to a certain regulated point; and it will also be seen that through the medium of the bandwheel K and the strap V, I am enabled to readily raise the pivoted or swinging section from the stock when desired. It will also be observed in the precedingdescription that in the tension-levers and weighted arms I have provided a medium whereby the embossingdie his allowed alimited yielding movement.

The lower dies 7i and h2 are carried by movable bearings or carriages o and o', and they are adjusted to suit various sizes of stocks by means of pinions 02,'which are mounted on a shaft-bearing in the carriages carrying the shafts of the embossing-rolls, and these pinions o2 mesh with the teeth or eogs of segmental bases or tracks p formed on the upper forward end of the bed or base a. By this construction it will be seen that the lower rolls 7L and h2 may be given a curvilinear receding and approaching motion on the segmental bases, and by the employment of such rollers I am enabled to operate upon round articles-such as stair-banisters and similar articles-the stock being allowed to turn while being operated upon by the engraving-die.

As better illustrated in Fig. l of the drawings, the `gearing actuatingthe lower embossing-dies 7L and h2 is connected together by means of a rod p, whereby when the adjustable bearings ot' said rolls are moved the train of gearing is not broken.

\Vhen the lower dies have been properly adjusted with respect to the stock to be operated upon, I secure the adjustable bearings or carriages thereof to the segments by means of bolts a2 or the like, which take th rough the bearings into apertures formed at intermediate points in the periphery of said segments; but I do not desire to limit m 7self to this construction for fixing the bearings on the segments, as it is obvious that any suitable devices might be employed for the purpose.

In Fig. 4 of the drawings I haveillustrated a diagram to show the relative positions of the embossing dies or rolls when used for very heavy work, and it will be observed that for this class ofwork I employin addition to the upper die 71 and the two lower dies 71, and 712a third lower die hi, which bears in movable bearings adjustable upon the segments p', and when it is desirable to accomplish the embossing with the top die alone a roller ofa diameter to carry the stock clear of the dies 71 and h2 is employed, and these dies, as are those illustrated in position upon the machine, are driven by the pulleys X, the gear X, and the train of gears illustrated.

In operation the lower embossing-dies it and h2 are adjusted to the size of the stock, and are secured in such position, as described.

rlhe pivoted section g is then raised a suliicient height, through the medium of the handwheel IV and the strap V, as described, to allow of the introduction of the stock between the dies, and from the construction described it will be seen that when the machine is set in motion and the dies are rotated the stock (indicated by IV) will be rotated between the dies until the desired result is attained.

From the foregoing description it will also be understood that when desired stock may be fed lengthwise through the machine, the opening S in the upright standard C being provided for that purpose.

IVhatIclaim as my invention, and desire to secure by Letters Patent, is-
